An operator was using artificial lift to produce from a well in the Paradox basin near Moab, Utah, when a bearing and arm broke on the beam pumping unit, causing the operation to shut down. The field is located near the entrance to a national park, and operations are closely monitored by regulatory authorities. The operator wanted a replacement pump with a smaller footprint in this environmentally sensitive area.

CAMLift unit provided 90% smaller footprint and fast installation

Schlumberger recommended its newest sucker rod pumping technology, the CAMLift hydraulic pumping unit, which has less than 10% the footprint of a conventional beam pump. The CAMLift unit required no site preparation and was installed in less than three hours compared with up to 20 hours for a conventional pumpjack unit, reducing installation time by as much as 85%. The entire installation only required a boom truck and two technicians—no special crews. The compact system was well-suited to the tight interwell distances, and its 30,000-lbm peak load capacity was comparable to conventional beam pumping units.

Operator more than doubled oil production without increasing cost per barrel

The ability to quickly adjust the stroke length and overall speed, as well as independently adjust the up and down speeds, enabled maximum pump fillage on every stroke. During testing, oil production increased from an average of 12 bbl/d to more than 30 bbl/d and subsequently stabilized at 25 bbl/d. Production costs per barrel remained unchanged while output more than doubled. Pleased with the improved economics, the operator requested Schlumberger to install two more CAMLift units.
